Finally the power supply modules arrived, and I could finish the layout. And sizes seems to be fine, and with enough clearance too. My first plan was to just use serial between the ESP8266 and Atmega329P, but I changed that to I2C instead, with a pair of BSS138 for level shifting. A bit more love to the silkscreen, and it looks […]

With some help from Peter van der Walt, I got some good results importing a BMP into Eagle. Just selecting a BMP and importing it, most often gives a bad and jagged result on the pcb, here is how I did some processing on the image before importing it. First, you need to download and install Gimp. Open the image in […]

Soooo… Months ago I started working on ESP8266 based projects. One of them is a simple PCB with a connector for mains voltage in, 100mA fuse on to provide a bit of protection, switching power supply to convert the mains power into 5V DC, a LDO linear 3v3 regulator to bring the 5V down do a voltage the ESP8266 likes, […]

When I design a PCB, I spend a lot of time looking at how the traces are looking, trying to find better routes, and wasting a lot of time because I made some connection wrong somewhere in the schematic… But having passed all that, the next big question is, will it fit in the box? Or maybe you just want […]

As some might have noticed, I made my own library for Eagle. In this library I got all the components I design myself, and my goal is to get all the parts I use into that, so if anyone finds my site, they will be able to both download the schematic and board files for eagle, and the library so […]
